SANITARY DRINKING-FAUCET.

Specification of Letters Patent.

Application filed August 30,

To all whom it may concern:

Be it known that I, LUTHER T. l-lAvvs, a citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented certain new and useful Improvements in Sanitary lJrinlting' l aucets, of which the following is a specification.

My invention relates to that class of soul tar v drinkingfauccts in which the delivery end of-the faucet pipe is provided with a ll"i(')lllll ,{llfll.tl enlargement, which prt vents the user from int-losing the part from which the water issues, within his mouth, and which induces and compels him to receive Such. faucets pron'lote cleanliness and prevent" contamination and. disease, and are, therefore, an adapted for public places, and especially for schools. Devices of this general type, especially those more properly termed fouutains-,,are usually more or less complex and costly in their construction. the reason lieing'il onnd in the endeavor to mart every p l, contingency of their use. especially in sel'mols, where the children are apt. to play with them. But these very endeavors result in. want. of simplicity, ditli The object of my invention is to provide a drinlcinggfaueet which While being perfectly sanitary is simple in its constructionl certain and otleetive in operation, and at, tractive in appearance, and which can be furnished at small cost.

To this end my invention consists in the novel construction and arrangement of parts which shall now describe and claim, referei'ic-e being had to the accompanying drawnjesin .l'1i .-Ih- 1 l igul'g l is-a side elevation, partly broken, of my sanitary drililting-faucet. Fig. Q'is. 'li antary view showing the use of a remo le throttling diaphragm.

l is the 'l'aueet-pipe, which, according to its situation and connection with the servicepipe is" l'ilopti'lj, shaped and directed to terminute in an upturned delivery end 2, the. extremity of which indicated at 3. Aromul the delivery end 2 is permanently titted, as for ext'unplc, by soldering joints, a mouth-guard enlargement. 4, which in its best form is substantially globular. The ex tremity 8 of the faucet pipe is substantially level with the top surface of the guard 4:,

the making of the close permanent joint, but this projection of said extremity is not such as to enable the (ll-hiker to inclose it with his n'iouth. The size of the guard 4 is also such as to prevent its inclosure by the mouth, so that in drinking there will be no chance to take. the faucet into the mouth, nor any ineliiuttion to even place the lips in contact;

with it.

is the service pipe, andfi is a T-coupling connecting the faucet pipe and service pi" B, said coupling carrying acontrolling vall'e indicatec at.- 7. Any suitable control may be had at this point, the form here indicated being a veil known type of self-closing cock or valve, which is opened by pressureon the handles and which closes when the pressure is relieved.

In'order to regulate the delivery; of the water from the extremity 3, both in pressure. Olflfi f and volume. I throttle the flow-at! a just back of the controlling valve 7. T T5358 best done by providing or forming thein terior of the Teonpling 6 with adiaphragm 8 in which there is made a port 9 of suitable diameter. Thus for "a given pressure, the jet. issuing from the faucet-pipe extremity, when the valve 7 is opened under the full compression of its handles, may be adjusted and rnulated in height and force, so that it; wil not rise" unduly nor with excessive pressure, thereby preventing splashing, and affording comfort. in drinking, ThlStEl'Ot' t-ling tliaphragm may or? a permanent one, as shown in Fig. 1, in case's-where the pressure in the service pipe is known and, therefore, can he initially provided for, or,'as shown in Fig. 2, the diaphragm, which is here indi cated by 8' may be a separate removable aperturod disk, fitted to the face of, a flange (5' in the Tcoupling the insertion efidiaphragms with different sizes of ports, according to the pressure, and to the height and force of the jet desired.

To use the device, the drinker opens the controlling valve 7, and will naturally observe for a moment the jet. which issues from the extremity 3, before heattempts to drink. During this momentary delay, the faucet will clear itself and drive. out any deleterious or contaminating matter which may have found lodgment in it. Then the user will either stop it off and place his mouth above the ext-remlty 3 and again allow the jet to come, or he will at once place lllS mouth over the jet from above, and by.

(3. This willprovide for lowering his head bring his mouth down upon the get to such a point as will be .convenient for him to drink, though. wlthout touching either the extremity 3 or the mouthguard enlargement 4. A suit-able'tray, bowl, sink or other waste receptacle, unnecessary herein to show, w'ill he used in connection with the, faucet, to receive the unused water and splash. Thus the device is well adapted for use in schools being cleanly and consequently sanitary. The control of the pres sure'and volume by. an arbitrary-initially defined throttling beyond the power or cntrol of the drinker to alter or change will prevent thoughtless and irresponsible pen sons from anyplayful use of the device, a

factwhich is ofimporta-nce in. schools. The

guard enlargenzient 4% being soldered orothen wise permanentlyattached to the faucet pipe vice.-, i Hav1ng thus *-;I"cla1m as new and desire to secure by Letcannot easily removed. This will preventrchildren from dismenihering the dedescribed my invention what ice pipe; a valve controlling said connection and ported diaphragm in said coupinig' connection'for throttling the fluid flow.

2. A drinirin faucet comprising a faucetpipe having elivery end; a separate substantially globular mouth-guard enlargement through-Which said delivery end passes and issues substantially level with its top,

said enlargement heingfitted to and around the delivery end of the faucet-pipe by per:

manent tight-joints; a connection for said.

faucetpipe' with the service-pipe; and a valve controlling said connection.

3. A drinkin -faucet'eon prising a faucet pipe having a 'elivery end; a separate permanentlyattached mouth-guard enlargement through which said delivery end passes and issues substantially l'eyel with its top;

said enlargement being fitted to and around I V the elivery end-oi the faucet-pipe by tightjoints a connection for said faucet pipe with the service pipe; and a valve controlling connection. i

ni'ent through which said delivery end passes and issues substantially level with its top;

the delivery end of the faucet pi e connect v ing directly with the upper end 0 the mouth.

guard enlargement by a closed joint; acoupling connection for said faucetpipe with the service pipe; a valve controlling said con-v 'neotion; and a ported diaphragm in said coupling connection for throttling the fluid flow.

5. A drinking-faucet comprising a faucetpipe having a delivery end, an. enlarged mouth guard sleeved upon the delivery end of the faucet pipe, wherebythe extreme,

outer end of the faucet-pipe is iii substantial alinemcnt with the outer end of the mouth gnzmi, the said mouthgnard connecting with otherwise free from openings. 7
